VENTILATOR-SASH MECHANIISM.

To all whom t may concern:

i Be it known that I, FRANK D. MOON, a citizen of the United States,residing at Edgewater, in the county of Bergen and State of New Jersey,have invented a new and useful Ventilator-Sash Mechanism, of which thefollowing is a specification.

My invention relates to improvements in mechanism for opening andclosing a con tinuous line or continuous lines of Ventilating or otherwindows or sashes, and the objects thereof are to provide means by whichsaid lines of windows may be operated from a single shaft, and from aconvenient point on the floor of the building; to provide means foroperating a part or all of said windows simultaneously, to provide forthev tight closing of said windows and further to provide automatictensioning means which will insure the operation of the mechanism fromthe shaft.

Other objects and advantages of my invention will appear from adescription of the par ticular embodiments thereof1 illustrated ih theaccompanying drawings in which- Figure l is a transverse sectional viewof a monitor roof provided with the mechanism; and Fig. 2 is a similarview showing a different form of the invention.

In the drawings, Fig. 1, my device is shown as applied to a so calledmonitor roof l such as is commonly employed for the ventilation andlighting of a factory building and which extends along the main roof 2of the building. Upon the central truss members 3 of the monitor` roofis mounted a central operating shaft 4 journaled in suitable bearings 5on said truss members. At intervals along the shaft, and in line witheach pair of opposite ventilating windows 6, cords or wire ropes 7 and 8extend between the sashes and around the shaft 4, preferably in severalturns, which by means of metal rods 9, 9, and 10, 10 are connectedrespectively to the upper and lower rails of the sashes as shown,although it is to be understood that the rods may, if desired, beomitted and the ropes eX- tend to and be fastened directly to thesashes.

To provide for the simultaneous opening and closing of the sashes onopposite sides of the roof, the cord 7 passes from the rod 9 at tachedto the u per end of the sash over and around the shafit) and to the rod9 attached to the lower end thereof, whereas cord 8 passes from the rod10 attached to the u per end of its sash, beneath and around the s aftand to Specification of Letters Patent.

Application filed January 18, 1907.

Patented Oct. 20, 1908.

Serial No. 352,957.

' the rod 10attached to the lower end of the sash, the free parts of thecord 8 crossing at 1l whereby revolution of shaft 4 in one `directionwill cause the simultaneous opening of the opposite sashes, whileopposite rotation of the shaft will close the sashes,

To maintain the proper tension on the operating cords to hold the sashessteady, the lower parts of the cords are provided, preferably at thejunction with the rods 9 and 10, with Weights 13, attached thereto inany suitable manner, by means of which the slack is taken up and thecords maintained at an equal and uniform tension. These weights moreovercause the lower ends of the sashes t0 be drawn tightly into their frameswhen the sashes are closed. A further function performed by the weights13 is to maintainL the coils of the cords tight upon the drum 4 in orderto insure positive operation of the sashes under normal conditions.

The tension of the cords around the shaft is such, however, that shouldone or more of the sashes be prevented from moving by the clogging ofsnow or otherwise, the cords thereof may slip upon the shaft thuspermitting the shaft 4 to rotate at all times to open and close theremaining sashes.

To operate the mechanism from any convenient point, such as the floor ofthe building, the shaft 4is provided at either end, and

if desired at intermediate points, with pulleys 14 around which passhand operating ropes or chains 15 which may extend to the floor or otherconvenient point of operation.

In the form of my invention illustrated in Fig. 2 of the drawings, thearrangement of the shaft 16, pulley 17, and hand rope 18 may be the sameas that shown in Fig. l. In this form of the invention however thesashes are operated by means of chains 19 and 20 respectively which passaround sprocket wheels 21, arranged upon the shaft `16 opposite eachpair of sashes 22 to be operated The arrangement of the chains issimilar to that of the cords in the former constructions to insuresimultaneous opening and closing of the opposite sashes. To avoidinterference of the free parts of the chains 20 at the point ofcrossing, the ends thereof may be attached to the upper and lower endsof thel sashes at points slightly out of vertical alinement. In thisconstruction also the weights 23 are provided to insure the tightclosing and uniform movement of the sashes in opening and closing.

lIO

Various Changes may be made in the arrangement of the parts withoutdeparting from the spirit and scope of the invention.

Claims.

1. In ventilator sash operating mechanism, the combination of arotatable shaft and means to operate the same, flexible connectionsbetween said shaft and sash and auto matie tensioning means on saidflexible oonnections to maintain uniform tension on said connections andto insure uniform opening and closing movement, and the tight closing ofsaid sash.

2'. ln ventilator sash operating mechanism, the combination of arotatable shaft and means to operate the same, 'flexible oonneotionsbetween said shaft and sash and weight attached to said flexibleconnections to 1naintain uniform tension on said connections andtoinsure uniform opening and closing movement, and the tight Closing ofsaid sash.

3. In ventilator .sash operating mechanism, the combination of aplurality of sashes and an operating shaft common thereto of iiexibleconnections between said sashes and shaft7 automatic tensioning means onsaid connections to maintain uniform tension on said connections, saidconnections also adapted and arranged to permit one or more of saidsashes to remain stationary while the others are moved to open or closedpositions.

n testimony whereof' I afIiX my signature in the presence of twowitnesses.

Vitnesses M. D. HART, RALPH C. POWELL.

It is hereby certified that in Letters Patentl No. 901,544, grantedOctober 20, 1908,

upon the application of Flank D. Moon, of Edgewater, New Jersey, for animprovement Ventilator-Sash Mechanism, errors appear requiring thefollowing corrections: In the drawings forming a part of said patentFig. 1 should read Fig. 2, and Fig. 2 should read Fig. 1; and that thesaid Letters Patent should be read with these corrections therein thatthe same may conform to the record of the case in the Patent Ofhce.
